1 Introduction
1.1 The proposal is to excavate construction waste from a site located north of Drope Road in the Vale of Glamorgan and west of Route A.4232. The materials will be transported to Barry Docks for storage:

1.2 This Transport Statement has been prepared at the request of the Vale of Glamorgan Council Highways Department. The proposed route passes through Cardiff City and discussions have been held with Highway Officers. The TS will show that there will be no significant impact on the local highway network by: Outlining the design of a new access junction with Drope Road: Illustrating how trucks will enter and leave using swept path analysis; Assessing vehicle speeds in Drope Road Identifying visibility splays; Reviewing the route to Barry Docks; Defining travel periods

2 Local Highway Network
2.1 The proposal is for the HGVs transporting the waste material to use Drope Road east of the access road. This is a single carriageway highway with a National Speed restriction and a width of approximately 6.4m:

ACCESS
DROPE ROAD

2.2 Some 100m west of the access to the site Drope Road crosses the Vale of Glamorgan boundary and enters Cardiff City. Shortly after crossing Route A 4232 a 30mph speed limit is in operation and in around 250m the road changes from rural to urban. Approximately 850m from the site access Drope Road joins Michaelston Road at an uncontrolled T-junction. On the south-west corner there is a group of education and community premises including St. Fagan’s Primary School, Ely and Caerau Children’s Centre, an Activity Centre and Michaelston Community College.
2.3 HGVs will turn right onto Michaelston Road and travel some 650m to a signalised junction and then turn right onto Route A.48. In approximately 150m at the Culverhouse Roundabout the HGVs will join Route A.4050. This road and the remainder of the route to Barry Docks are in the Vale of Glamorgan. The route is ______3 C2362-TS01D Traffic and Transport Planning September 2016 Drope Road, Drope Transport Statement ______
well used by HGVs and will be suitable for the proposed transport of waste material. The overall route is around 12km and there are no restrictions on use by HGVs:

3 Proposed Development
3.1 The main section of the application site is currently in use for rough grazing but the area to be used for access (the 'Janes' site) is used currently for unloading, sorting and loading various materials. These are transported by HGVs and it is understood that usually they make three or four trips per day in both directions The storage and loading/unloading area is surfaced with hard-core. The access lane is an unmade track around 3.7m wide. There are no wheel-washing facilities installed. The Applicant has negotiated use of this access lane and during the operation will be the sole user. Before work commences on the proposed development the existing materials in the access lane and storage area will be removed and the site cleared.
3.2 The proposed excavation works will be over a three year period with around10-15 HGV trips per day to Barry Docks. Operating hours will be between 0800 and 1630hrs Monday to Friday and 0800 to 1300hrs on Saturday. No work will take place on Sundays or Bank Holidays. During a school term there will be no movements to and from the site between 0830 / 0930 and1500 / 1600hrs subject to agreement with the Highway Authority.
3.3 The unmade access lane will be widened to 6.1m and surfaced with hard-core. The proposed junction with the haul road will be designed to highway standards. A left- turn only sign will be erected to ensure that all vehicles turn left into Drope Road and the turning radius will be 15m:

3.4 Two Scania tipper trucks will be used. The on-site project manager will organise arrivals and departures for all vehicles and there will be radio communication with the drivers. This will ensure that the HGVs do not use the section of Drope Road adjacent to the site at the same time. A wheel washer will be installed adjacent to the haul road.
3.5 The loading compound will be constructed to enable HGV’s to load and leave the site travelling in a forward direction. On-site there will be an excavator and bucket loader – these will not leave the site during the three year period.
3.6 Security will operate at the site on a 24/7 basis throughout the project.
4 Access Junction
4.1 The improvements to the existing access as shown in Fig 4 will remain following completion of the project.
4.2 Traffic speed data shows that the five day average for vehicles travelling eastbound is 38.8mph and westbound 38mph (Appendix A). MfS2 Para 1.3.7 states: ‘…in rural areas many parts of the highway network are subject to the national speed limit but have traffic speed s significantly below 60mph. Again in these situations where speeds are lower than 40mph, MfS SSD parameters are recommended.’
4.3 A topographical survey carried out of the junction with Drope Road identifies the visibility splays in both directions as over 2.4x100m. These are greater than the MfS recommended maximum value of 56m (Appendix B).
4.4 Swept paths show that a Scania tipper truck will be able to negotiate the proposed improved junction:
